Senate Democrats blocked the House-passed Stop Insider Trading Act in a 53-47 procedural vote on September 30, 2026, falling short of the 60 votes needed to advance amid disputes over its limited scope, which would bar new stock purchases but allow retention of existing holdings, family trading, and exemptions for the executive branch. Partisan divisions, including attached voter ID provisions and demands for a fuller divestiture requirement, have repeatedly stalled broader reforms despite public polling on the issue and prior House action. With midterms approaching and the current session winding down, traders see slim prospects for legislative consensus or floor time sufficient to enact any ban before 2027. A post-election shift in chamber control or a major ethics scandal could still reopen the debate in a lame-duck period.
